Police have identified the suspect responsible for Friday's night shooting rampage at University of California, Santa Barbara that left seven people dead, including himself. Elliot Rodger was a lonely 22-year-old student at the school who felt alienated and reject, especially by women. Prior to the shooting, on Friday, he posted eight videos on YouTube detailing his anger, frustrations, and plans for retribution.

"I don't know why you girls haven't been attracted to me, but I will punish you, for it is an injustice," he said in one video. "I'll take great pleasure in slaughtering all of you.” He also wrote an 137-page rant called "My Twisted World: The Story of Elliot Rodger," in which he states “If only one pretty girl had shown some form of attraction to me, the Day of Retribution would never happen. I'd never even consider it.” Rodgers reportedly first stabbed to death his three roommates, killed two women and injured one at a sorority house, and then fired at random people before appearing to take his own life. In addition to the seven fatalities, 13 people were injured. Police say Rodgers was found with a Glock 34 and two Sig Sauer P226s and more than 400 rounds of ammunition.
